Deploy dependent assemblies easily using PAC CLI

Hi Folks,

This is another post related to Plugins in Dynamics 365 CE.

Considering medium to large scale implementations, there isn’t a single Power Platform Project which don’t require merging of external assemblies.

We relied on ILMerge to merge those assemblies into a single DLL. We used to search for ILMerge assemblies in Nuget and installed them for use.

Then the plugins are signed in for several reasons, primarily related to security, assembly integrity, and versioning of the sandbox worker process.

But either of the above are no longer needed with the help of Dependent Assembly feature…with few simple steps, you can build the Plugin…Interesting, isn’t it, read on…

Pre requisites:

  • Download Visual Studio 2022 Community Edition here
  • Download VS Code from here
  • Download Plugin registration tool from here
  • Download PAC CLI from here
  • Download and install NuGet Package Explorer from this link NuGet Package Explorer open the NuGet Package Explorer

Avoid Direct Plugin Project Creation in Visual Studio

  • Never create a Plugin project directly from Visual Studio or any other IDE here after.
Use Microsoft PowerApps CLI instead
  • Always use Power Apps CLI as it easy and only requires a single command to create the entire Plugin project scaffolding
  • This ensures a standardized and reliable development environment.
  • It automatically creates a Nuget Package file that will be used to avoid ‘Could not load assemblies or its dependencies‘.

Ok, let’s begin.

Once you have downloaded all the prerequisites mentioned, make sure you have installed them in your local machine. Others are straight forward to download, for NuGet Package explorer, you need to search in Windows store to install.

  1. Create a local folder for the Plugins

Navigate to that folder from VS Code

Now open terminal, run the pac command as below

Execute the following command to create plugin project 

  • Browse to the directory where you want to create the plugin project
  • Execute the command on CMD to create plugin project “pac plugin init“

A plugin project will be created at your desired location as follows

Plugin project in local folder will be created as below

That’s it, you can close the VS Code for now.

Click on the CS Proj file and open it in Visual Studio

By default, 2 files are automatically created when you create a plugin project as shown above.

Now will install Bouncy Castle which is an external library, right click on the Plugin Solution –> Manage Nuge Packages

I have added Bouncy Castle NuGet Package to my plugin project for Encryption and Decryption. You can have your own required NuGet Package as per your need.

Build your project

After a successful build, you will get the output result as follows

Browse the directory of your project

Open the file Plugin_Project.1.0.0.nupkg in Nuget Package Explorer by double clicking it

Now you can see that this nuget package file contains the information related to the added nuget package of Bouncy Castle that we want to include in our plugin project package as follows. In your case, you can have the required nuget package that you want to add 

Now open up plugin registration tool

Click to create new connection

Provide login details and login

Click to Register New Package

Browse to the directory where your nuget package file was created automatically when you build the project and import this file 

Select the Command Data Service Default Solution and import it

Click on view and Display by package

Now your Plugin Project is successfully registered with all dependent assemblies and ready to use.

While this post gives you a structure on how you can do build a plugin assembly, you can add the business logic as per your need.

Conclusion:

In conclusion, navigating the intricacies of Microsoft Dynamics 365 CRM plugins demands a nuanced approach, especially when dealing with NuGet Packages and dependent assemblies. This article has delved into the critical process of resolving the persistent ‘Could not load assemblies or its dependencies‘ issue, offering a comprehensive, step-by-step demonstration.

By following the recommended best practices, such as avoiding direct plugin project creation in Visual Studio and harnessing the power of Microsoft PowerApps CLI, developers can establish a standardized and reliable development environment. The CLI’s automatic creation of a NuGet Package file not only streamlines the process but also reduces the errors.

To further facilitate your journey, prerequisites such as downloading and installing essential tools like the Plugin Registration tool, Microsoft PowerApps CLI, and NuGet Package Explorer are highlighted. The guide emphasizes the significance of these tools in ensuring a smooth plugin development experience.

By adopting these practices and incorporating the suggested steps into your workflow, you not only troubleshoot existing issues but also fortify your understanding of the entire process. Take charge of your Dynamics 365 CRM plugin development, elevate your skills, and sidestep common pitfalls by mastering the art of handling NuGet Packages and dependencies seamlessly.

Microsoft Power Platform Center of Excellence (CoE) Starter Kit – Core Components – Setup wizard – Learn COE #02

Hi Folks,

This post is continuation to my previous post on COE Starter Kit, if in case you have just landed on this page. I would suggest go here and check out my blog post on introduction to COE Starter Kit.

Important:

Do test out each and every component, rolling out to production without testing as you need to keep in mind that there were many flows which can trigger emails to users which may keep them annoyed.

You need to install the components present in the COE Starter Kit extracted folder in the dedicated environment, preferably Sandbox environment (not in Default environment, so that you can test it out first before moving changes to Production), make sure you have Dataverse installed in the environment. First let’s install the Solutions and later we can proceed to customize them.

Install CenterofExcellenceCoreComponents managed solution from your extracted folder, the exact version may be different and differ as the time goes at the time of installing this, the version was as below CenterofExcellenceCoreComponents_4.24_managed

Then proceed to click on Import as we will be configuring these environment variables whenever required later. It takes a couple of seconds to process, it asks to set the connections which I had talked about in previous post, just create new connection if one not available and click next. Make sure you have green checkboxes for each connection, and you are good to click next.

Then you will be presented with the screen to input Environment variables as below, we will configure later so for now, just proceed by clicking on Import button.

The import process may take a while like around 15 minutes, once imported, you should see a notification message on your screen something like below.

Step 1:

You will have a bunch of Apps, Flows installed in your environment. Configure the COE Settings by opening the Centre of Excellence setup and upgrade wizard from the installed Center of Excellence – Core Components managed solution.

It should look something like below when opened. You will be presented with some prerequisites

Proceed with this step-by-step configuration, you don’t need to change any of the setting, just proceed by clicking on Next.

Step 2: In this step, you can configure different communication groups to coordinate by creating different personas

You can click on Configure group, choose the group from the drop down and enter the details and click create a group.

Provide a group name and email address without domain in the next steps and proceed to create a group, these were actually Microsoft 365 groups.

Once you have setup, it should show..

However, this step is optional, but for efficient tracking and maximum benefit of COE, it is recommended to set this up.

Step 3: While the tenant Id gets populated automatically. Make sure to select no here instead of yes if you were using Sandbox or Production Environment and configure your Admin email and click Next.

Step 4: Configure the inventory data source.

Tip: In case you were not able to see the entire content in the page, you can minimize the Copilot and press F11 so that entire text in the page would be visible to you.

This is required for the Power Platform Admin Connectors to crawl your tenant data and store them in Dataverse tables. This is similar to how search engines crawl entire internet to show any search results. While Data export is in preview, so we proceed with using Cloud flows.

Click Next.

Step 5:

This step is Run the setup flows, click on refresh to start the process. In the background, all the necessary admin flows will be running. Refresh again after 15 minutes to see all the 3 admin flows are running and collecting your tenant data as below and click Next.

Step 6:

In the next step, make sure you set all the inventory flows to On.

By the way inventory flows are a set of flows that are repeatedly gathering a lot of information about your Power Platform tenant. This includes all Canvas Apps, Model Driven Apps, Power Pages, Cloud Flows, Desktop Flows, Power Virtual Agent Bots, Connectors, Solutions and even more.

To enable them, open the COE Admin Command Center App from Center of Excellence – Core Components Solution. Make sure you turn on all the flows available.

So, after turning on all the flows, come back and check on Center of Excellence Wizard Setup, you should see a message something like below saying all flows have been turned on.

Configure data flows is optional, as we haven’t configured it earlier, this step would be skipped.

Step 7: In the next step, all the Apps came in with Power Platform COE Kit should be shared accordingly based on your actual requirement to different. personas.

Step 8:

This part of the wizard currently consists of a collection of links to resources, helping to configure and use the Power BI Dashboards included in the CoE.

Finish

Once you click Done, you will be presented with more features to setup.

These setups have similar structure but varies a bit based on the feature architecture.

As we got started with setting Starter Kit and had set up the Core Components of the Starter Kit which is important one, now you can keep customizing further, in the future posts, we will see how we can set up Center of Excellence – Governance Components, Center of Excellence – Innovation Backlog. These components are required to finally set up the Power BI Dashboard and use effectively to plan your strategy.

Everyone who’s ever installed or updated the CoE knows how time-consuming it can be. Not just the setup procedure, but also the learning process, the evaluation and finally the configuration and adoption of new features. It’s definitely challenging to keep up with all this. Especially since new features are delivered almost every month. This attempt from me is to try my best to keep it concise, yet making you understand the process.

While such setup wizard is clear and handy resource to get an overview of the CoE architecture and a great starting point for finding any documentation. This simplifies administration, operations, maintenance and may be even customizations.

If you face issues using the COE Starter Kit, you can always report them at https://aka.ms/coe-starter-kit-issues

Hope this helps…. someone setting up COE starter kit…. if you have any feedback or questions, do let me know in comments….

Cheers,
